Introduction Manipulators are widely used in engineering fields to raise the productivity and improve the quality of products.
Therefore, they have been widely used in engineering fields, among which tuned mass dampers [2], tuned liquid dampers [3], viscoelastic dampers [4] and impact dampers [5] are the most representative.
Theoretically, impacts can be exactly depicted by means of the modern contact dynamics in mathematics, but it is too complicate to apply in engineering fields.

Since satellite positioning technology been used in forestry, many domestic experts and scholars are working on the application research of satellite positioning technology in forestry, all the application can be summarized as follows[1][2][3]:1) Investigation and management of forest resources, such as, plot investigation, forestry distribution detection, measurement of forest area, cutting area design and monitoring; 2) Forestry engineering survey; 3) Afforestation, including aerial seeding, forest classification and survey;4) Forest fire, including the fire position, area measurement and evaluation of forest fire; 5) Wile animal monitoring and protection; 6) Forest tourism and expeditions. 1.2 Problems Satellite positioning technology has been used to our forestry area, but there exist many problems in practical application, such as, poor signal, low positioning efficiency and low accuracy, so that part of the business which call for position can’t be done, especially in south of
Not only can we improve the precision of the forestry, but also to reduce unnecessary waste of time and material resources by this technology.
(10) (11) 3.3 Key Technologies If we want to combine ground positioning technology and satellite positioning technology, and apply it to forestry business, we should solve several primary technologies: ①Time Synchronize of satellite positioning and ground positioning.

A modified ecological footprint model and its application in hydropower project Chenglong He1,2 1 College of Water Conservancy and Hydropower Engineering, HoHai University, Nanjing, China 210098 2 College of Civil Engineering & Architecture, JiaXing University, Jiaxing, China 314001 E-mail:zjxuhcl@126.com Keywords: Emergy analysis; Ecological Footprint; Basin emergy density; Hydropower project Abstract.
Emergy provides a numeric framework for comparison of different forms of energy and materials.
The transformity is a key parameter in emergy analysis theory.
The material consumption, such as cement, steel, timber and explosives is 2.77 × 105, 4.17 × 104, 2.71 × 104 and 3.00× 102 tons, respectively.
According to the modified model, the ecological footprint occupied account is composed of the material consumption and construction mechanical energy consumption mainly before the design equilibrium year.

The standard for ferritic heat resistant cast iron of the automobile exhaust manifold by the Society of Automotive Engineers specifies the Si content to be 4.0wt% [1].
However, the problem is that the limit of Si composition in Fe matrix is around 6wt%, and the material becomes more brittle as the composition approaches the limit.
This study intends to evaluate how the thermal stability changes according to the content of Si, which is the key element of the ferritic heat-resistant ductile iron.
